The code is P0420. You Probably need a catalytic converter. It is covered under the federal emissions warranty.
If you look in the owners manual, I believe emission components are covered for 100,000 miles (or somewhere around there).Thanks Mike, can you explain further how or why it would be covered? I have had so much fixed on this truck under warranty, now my extended warranty is gone (passed 60,000 miles). Appreciate any feedback
Emissions are 8yr/80k so the OP is good. Just take it to your dealer, have them pull the code and they will replace your CAT or CATs. What happens is they get clogged with crap or breakdown. Pieces end up getting sucked back into the motor and it craps out. It has happened to a few VQs and VKs in the past. This is why some have opted to go HF cats with headers (performance and CAT insurance).If you look in the owners manual, I believe emission components are covered for 100,000 miles (or somewhere around there).
